Animals turning into zombies is a phenomenon that may seem like something out of a horror movie, but it actually occurs in nature. The article discusses fifteen factors that can turn animals into zombies. These include parasites such as toxoplasma gondii, which alters the behavior of rats and makes them more likely to be eaten by cats, allowing the parasite to reproduce. Other factors include brain parasites, such as the lancet liver fluke, that manipulate ants into sacrificing themselves for the parasite's benefit.
